Acceleration Due to Gravity Problem **HELP**

Homework Statement

Titania, the largest moon of the planet Uranus, has 1/8 the radius of the Earth and 1/1700 the mass of the earth...

What is the acceleration due to gravity at the surface of Titania? (m/s^2)

Homework Equations

g= GMe/Re^2

(Me) mass of planet
(Re) radius of planet
